Indeed, and the grammatical use of Punycode in this sentence is actually wrong.
"Punycode is an Algorithm, Not a Name or Adjective" (https://tools.ietf.org/html/rfc5890#section-2.3.4)

The informative reference would be RFC 3492 but the text should be something closer to
"a Discovery Proxy does no translation between Punycode-encoded strings and UTF-8 strings", or
probably more correctly "a Discovery Proxy does no translation between A-labels and U-labels".
